Apnlicntion tiled February e, 1911. Serial No. GO'LLEBV To all whom 'it 'moy concern:

. Pe it. known that It, thermen dnn'rzscn, :i eitlzen ot' the. United States,residing et; Chi cago, in the connty of Coole; and

illinois, have invented new end useui 11nproements in tlellteeteining Uterine- Tnbes, (nl which the following 1s e specificetion.

and noxious*Y matters to continually pass ont of .the Wonen, -iivithout dison'ifor i to the user.

thereby assuring a healthy condition to the orga-n.

Another object of the invention is the provision of av tube ot this character, in which the periodical menstruati-'ni tion' oa womb will not be interfered with, or in any manner impeded, and that will correct any deviation therein, giving tothe uterus and its append ages a perfect drainage, and allowinu all broken down or diseased tissues to ti-rely pass ont of the womb, and also other noxious matters, thereby leaving the woinh in a strong, clean and healthv condition.

A further object of `the invention is the provision of a tube of this character which may he readily and easily inserted in the uterus, for retention therein. and that will not irritate the membrane or falls tl'lereot` the tube being simple otf construction, indestructible, light, reliable and eiicient` in operation, and iiiexpensive in manufacture.

With these and other objects in View, the invention consists in the construction, combination and zii-rangementv of parts, as Wvitill be hereinafter more fully described, illustrated in the accompanying drawings, and pointed ont in the claims hereunto appended.

Similar reference characters indicate corn responding parts throughout tl'pe several Referring to the drawings 'ny nfiinffnals, F3

designates n vagine, and 9 the uterus having its cavity 10, in which is titted the uterine ruhe, as will be hereinetter fully described. This 'uterine tuheornpriees e. tubular body or shell 1.1, constructed from e. suitable nonirritating and indestructible innterial, pieten ably silver, or similar alloy, having;f a central bore 12 therein, tapering toward one 'end ot said body or shell. the latter ,being also tunered toward one of its ends correspondingly to the taper ot' said bore 12 therein. The larger end ot said body or shell 11 is provided with a flared annular flange 13, While the opposite smaller end is provided With an onttnrned rounded annular lia-nge 14, the lang'es 13 `and 14, respectively, being pr0- vided With concnved inner walls 15.

At-diametrically opposite points, of the body or shell l1. intermediate its ends, are 'provided orifices 1G, the 'same being interseetetl by longitudinally disposed slits 17 arranged.directly opposite each other, and I open ng through the smaller end of said body or shell and severing said lanfe 14, to nror de hendable Senn-circular shaped retaining' legs vor extensions 18, which are -adap ed to be outwardly deflected in diVerg.-.

inn relation to each other for retaining the hoo;T or shell 1l within the uterus when positioned therein in a manner as will be hereinafter more fully described.

The mode of applying the device is as follows: rfhe uterine tube norn'ially in the position as .shown in Fie'. Q ot the drawings, so that the body or shell lt can be easily inserted in the` 'vagina for inpinging it in the cavity l0 ot the uterus Sl, without tearing" or otherwise injuring the lining; of the womb. Thus the tube will be passed therel in without causing pain to the patient. Any suits-tbl@ instrument is eliiploved for' inserting the uterine ubefwhich latter is passed into the uterine oarity 10, so thaty the larger end of the body or shell l1 will lie in the internal os of .the uterus, whereupon the retaining legs or extensions 18 are separated from each other, so that tiresome will inwftrdly diverge, thereby flnring the smaller end o'lt the body or shell l1, causing' the flange 14 on the extremities of the legs or extensions 18 to impinge with the Aparnlual Wells of the uterus, above the internal os, so that on contraction of the external os to normal about. the body or shell 1l, the latter will be perfectly held in place inv the cavity in the uterus for the proper ilrainage thereof, whereby allowing eiete r noxious matters and also diseased or i'ot be interfered with, and that the tube will be self retained within the uterus, without possibility of accidental displacement or the dropping thereof from the Vagina.-

From the foregoing description, taken in Yconnection with the accompanying drawings, it is thought that the construction and operationof the invention will be readily understood without requiring a more extended explanation, and therefore the same has been omitted. 'K

What is claimed is:

As an article of manufacture, a self retaining-uterine tube comprising a tubiform body having an end portion tapering outwardly from a point spaced from the inter mediate portion of said tube, the said tapered end being provded'at diametrically opposite points with slits and also with circular orifices at the inner ends of said slits to provide separable semioircular-shaped retaining legs adapted to be flared in diverging relation with respect to each other, a flared annular. Hange formed at the larger end of the tube and having a rounded edge, and outturned rounded semi-annular flanges formed on the legs at the free edges thereof.

In testimony. whereof I aiix my signature in presence of two Witnesses.
